WASHINGTON — President Trump is matching a human face to his super-charged rhetoric on North Korea by meeting with several defectors from the country in the Oval Office on Friday.

Among the guests: Ji Seong-ho, who Trump lauded at his State of the Union speech on Tuesday. Ji lost a leg and an arm while scavenging coal as a boy, and later fled to South Korea.

Trump used Ji's story to illustrate what he called the "depraved character of the North Korean regime" and the kind of threat it could pose to the United States and its allies if it obtains nuclear weapons. Friday's meeting was announced in the president's schedule.

During the meeting, Trump asked the defectors to tell their stories — some using a translator while others spoke about their experiences in English. After each story, Trump replied with phrases like “tough stuff,” and congratulated the defectors on their freedom.

Hyeonseo Lee, another defector who met with Trump, said escaping from North Korea is not like leaving another country.

“It's more like leaving another universe. I will never truly be free of its gravity no matter how far I journey. After I escaped to China, I escaped an arranged marriage when I was 19, and I also escaped a brothel. And eventually, I was arrested by the Chinese police, but narrowly avoided being repatriated back to North Korea because of my Chinese language abilities. They couldn't believe that I was a North Korean defector," she said.
